Why did my Reverse NS lookup return no results?

Reverse NS lookup accepts will return up to 1,000 domains which pointed to a name server, however if a Reverse NS lookup returns no matching results, this indicates that there are no domains pointed towards the name server entered. If no matching results are shown for a Reverse NS lookup that you believe should have returned matches, please contact our support team with details of the name server and any known domains pointed to it.
